Shot one.
I would say that MTP is a very good overall cam scheme.
There is no particular cammo that works well in a field, which is why soldiers add local foliage to themselves.
DPM was designed to a very different criteria and while it worked well in its ideal setting (less than 75 metres in deciduous woodland) it appeared as a dark shape at longer distances.
MTP is good in many environments and at all kinds of observed ranges. One reason it would have stood out on the TV programme you saw is that the show was filmed with digital cameras. Although the MTP would have been different to the surroundings you saw it may have been less so viewed with the naked eye.
German Flektarn cammo can also appear very bright and orangey when filmed with a digital camera, but is a very effective cam when viewed with the naked eye.
All that said, many people don't like the newest MTP uniforms as they don't like the pocket arrangement etc, but then many naysayers of the new uniform don't wear it on patrol/front line either. Once you are wearing body armour and have several pouches around you the lack of a decent chest picket for fags or choccy becomes a non event.
